Ohm's law lab

Lab Report - Due in Classroom


Purpose - Find the relationship between resistance and current and voltage.

Materials - Circuit board and Variable Voltage Supply (include picture of set-up)

Data - Record data on provided sheets. Put onto spreadsheet and cut and paste into document

Graphs -
1. Current vs. Resistance
2. Current vs. Voltage

Determine relationships and straighten as needed.


Calculations
Determine slopes and formulas.
Percent error on slopes of all graphs vs. constant values (voltage or resistance)

Questions
1. What was the relationships between resistance and current?
2. What is the relationship between voltage and current?

Conclusion - Regular expectations

FYI -
voltages is joules/coulomb
ampere is coulomb/second
